Clinical analysis of distal radius core decompression for chronic wrist pain / 中国修复重建外科杂志

OBJECTIVE@#To investigate the effectiveness of distal radius core decompression in the treatment of chronic wrist pain caused by various etiologies.@*METHODS@#A retrospective analysis was performed for the clinical data of 10 patients with chronic wrist pain treated with distal radial core decompression between January 2018 and December 2021. There were 6 males and 4 females with an average age of 37.4 years (range, 21-55 years). The disease duration ranged from 7 to 72 months, with an average of 26.5 months. Preoperative MRI examination showed that 10 cases had bone marrow edema at the distal radius on the affected side, and 8 cases had bone marrow edema in the carpal bones such as scaphoid and lunate bone. Among them, 3 patients had a history of wrist fracture, and 2 patients had Kienböck diseases (1 case each in stage ⅡB and stage ⅢA). Three cases were combined with triangular fibrocartilage complex (TFCC) type 1A injury. Two cases were combined with osteoarthritis, 1 of them was complicated with severe traumatic arthritis, the wrist arthroscopy showed that the TFCC was completely lost and could not be repaired, and the cartilage of the lunate bone and the ulnar head were severely worn.Visual analogue scale (VAS) score was used to evaluate the relief of wrist pain before operation, at 6 months after operation, and at last follow-up, and the range of motion of the affected wrist in dorsiflexion, palmar flexion, ulnar deviation, and radial deviation was measured. The degree of bone marrow edema was evaluated according to T1WI, T2WI, and STIR sequences of MRI.@*RESULTS@#All the patients were followed up 12-22 months, with an average of 16.4 months. Except for 1 patient who experienced persistent wrist joint pain and limited mobility after operation, the remaining 9 patients showed significant improvement in pain symptoms and wrist joint mobility. The VAS score and range of motion of wrist dorsiflexion, palmar flexion, ulnar deviation, and radial deviation at 6 months after operation and at last follow-up were significantly improved when compared with those before operation, the VAS score and the range of motion of wrist ulnar deviation and radial deviation at last follow-up were further improved when compared with those at 6 months after operation, all showing significant differences ( P<0.05). There was no significant difference in wrist dorsiflexion and palmar flexion between at 6 months after operation and at last follow-up ( P>0.05). Bone marrow edema was improved in 6 patients on MRI at 6 months after operation, and was also improved in other patients at last follow-up.@*CONCLUSION@#For chronic wrist pain caused by a variety of causes, distal radius core decompression can directly reduce the pressure of the medullary cavity of the distal radius, improve the blood supply of the corresponding distal structure, significantly alleviate chronic wrist pain, and provide an option for clinical treatment.

Bone Scintigraphy in the Diagnosis of Rheumatoid Arthritis: Is There Additional Value of Bone Scintigraphy with Blood Pool Phase over Conventional Bone Scintigraphy?

We aimed to investigate the value of bone scintigraphy with additional blood pool phase (BSBP), compared with conventional bone scintigraphy (CBS), in the assessment of rheumatoid arthritis (RA). A total of 242 patients (43 males, 199 females; 14-78 years) with arthralgia, and underwent BSBP were retrospectively analyzed. On the first physical examination, active arthritis was found in 128 of the 242 patients. Clinical diagnosis was made by a rheumatologist on the basis of the 1987 American College of Rheumatology (ACR) criteria, which are considered to be the gold standard. The diagnostic performances and prognostic value of BSBP and CBS were analyzed in the total patients with arthralgia and in the patients with arthritis. The sensitivity of BSBP (84.2%, 80/95) were significantly higher than that of CBS (74.8%, 72/95) in the patients with arthralgia (P = 0.039). When BSBP was interpreted with the results of elevated/positive anti-CCP antibody, its accuracy over CBS also became significantly higher (86.0%, 208/242 vs. 83.1%, 201/242 respectively, P = 0.021). The diagnostic odds ratio of BSBP positivity was higher than CBS positivity in the patients with arthralgia (26.0, 12.9-52.4 vs. 21.1, 10.8-41.3) and with arthritis (12.0, 4.9-29.4 vs. 10.0, 4.2-23.4). Both BSBP and CBS appear to provide acceptable accuracy and comparable diagnostic performance for diagnosis of RA. However, in the patients with arthralgia, BSBP was found to be more sensitive than CBS and more accurate when interpreted with the result of anti-CCP antibody. This could help physicians diagnose RA in daily clinical practice.

Three Cases of Spondyloepiphyseal Dysplasia Tarda in One Korean Family

Spondyloepiphyseal dysplasia (SED) tarda is an inherited skeletal arthropathy. Because SED tarda involves the joints and resemble the clinical findings of chronic arthropathies, this disease is frequently misdiagnosed as juvenile idiopathic arthritis (JIA). We report here on three patients (father and his two daughters) in one family with SED tarda. All patients had back pain and polyarthralgia. Their radiographs revealed typical changes for SED tarda including platyspondyly and dysplastic bone changes. This rare disease has major clinical importance in that it is similar with JIA or rheumatoid arthritis.

Aluminio en pacientes con terapia de reemplazo renal crónico con hemodiálisis en dos unidades renales en Bogotá / Aluminium in chronic renal replacement therapy patients undergoing haemodialysis in two renal units in Bogotá

Objetivo Determinar las concentraciones de aluminio en suero de pacientes con terapia de reemplazo renal crónico con hemodiálisis y las concentraciones en agua de redes de distribución y diálisis en dos unidades renales en Bogotá. Material y Métodos Estudio descriptivo en 63 pacientes en hemodiálisis y 20 individuos sanos. Las concentraciones de aluminio se determinaron por espectrofotometría de absorción atómica horno de grafito con corrección de lámpara de deuterio. Resultados El promedio de las concentraciones de aluminio en suero de los pacientes fue de 26,5 µg/L (11,2 a 49,2 µg/L, DE=8,03), en individuos sanos de 8,05 µg/L (menor al Límite de Detección a 17,2 µg/L, DE=4,31), en agua de diálisis fue menor a 2 µg/L y en agua de las redes de distribución menor a 200 µg/L. Conclusiones Las concentraciones de aluminio en el agua de la red de distribución y diálisis estudiadas se encontraron por debajo de los valores establecidos internacionalmente indicando un adecuado tratamiento de las mismas. Igualmente las concentraciones de aluminio pre-HD y post-HD observadas en los pacientes se encontraron por debajo de las reportadas en la literatura. El consumo de hidróxido de aluminio aumenta significativamente la concentración de aluminio en suero. Variables como edad, género, estado civil y situación laboral no son factores de riesgo que alteren significativamente las concentraciones de aluminio en suero.

Objective Determining aluminium concentrations in the serum of patients undergoing chronic renal replacement therapy with haemodialysis and concentration in distribution network water and dialysis in two renal units in Bogotá. Material and Methods This was a descriptive study of 63 haemodialysed patients and 20 healthy subjects. Aluminium concentration was determined in water and serum using graphite furnace atomic absorption spectrometry with deuterium lamp background corrector. Results Average aluminium concentration was 26.5 µg/L in patients (ranging from 11.2 to 49.2 µg/L; 8.03 standard deviation) and 8.05 µg/L in healthy individuals (ranging from undetectable to 17.2 µg/L; 4.31 standard deviation). Aluminium concentration in dialysis water and distribution network water was below 2 µg/L and 200 µg/L, respectively. Conclusions Aluminium concentration in water and serum in this study was below international standard values, thereby indicating appropriate treatment. Additionally, aluminium concentration in pre-HD and post-HD sera was below that reported previously. Aluminium hydroxide uptake increases aluminium concentration in serum. Personal situation regarding age, gender, civil and work status were not risk factors determining aluminium concentrations in serum.

Manifestações articulares da febre reumática / Articular involvement in rheumatic fever

A artrite é a manifestação clínica mais freqüente, mas menos específica, da febre reumática. Alguns pacientes podem apresentar quadros articulares atípicos, diferentes da poliartrite migratória clássica descrita por Jones, o que dificulta a identificação dessa doença, principalmente quando o paciente apresenta artrite como único sinal maior.
